Mobtakeri, Soheil; Akaltun, Yunus; Özer, Ali; Kılıç, Merhan; Şenadım Tüzemen, Ebru; Gür, Emre (2021)In this study, gallium oxide (Ga2O3) thin films were deposited on sapphire and n-Si substrates using Ga2O3 target by radio frequency magnetron sputtering (RFMS) at substrate temperature of 300 ◦C at variable RF power ... -
Incorporation of graphene oxide to metal-free phthalocyanine through hydrogen bonding for optoelectronic applications: An experimental and computational study
Yabaş, Ebru; Şenadım Tüzemen, Ebru; Kaya,Savaş; Maslov, Michael M.; Erden, Fuat (WILEY, 2023)This paper focuses on incorporation of graphene oxide (GO) to metal-free phthalocyanine (MPc) through only hydrogen bonding and π-π stacking. Briefly, Pc-GO composites at various concentrations were prepared by selfassembly ... -
Investigation of nitrogen doped ZnO thin films: Effects on their structural and optical properties
Un-doped and nitrogen-doped ZnO thin films were grown by using radio frequency (RF) magnetron sputtering method changing the nitrogen flow rate between 0% ����� 12.5% and the thickness dependence of films was determined. ... -
Investigation of optical, electronic, and magnetic properties of p-type NiO thin film on different substrates
In this study, high-quality p-type NiO semiconductor thin film was investigated using the thermal evaporation method after thermal oxidation of as-deposited 50 nm Ni film at 450◦C for 2.5 h. NiO thin film simultaneously ... -
